Analyzing The Structure, Synthesis, Function, Distribution, And Potential Uses Of Magnetosomes

We are currently in the process of finding magnetic properties of iron and nickel samples for their use and application in small-scale electronic and magnetic storage devices. I have presented posters on my findings in postern form which I carried at Cornell University and on the Methodology of Elemental Analysis Lab in Food and Drug Administration (Arsenic in rice speciation) at the Undergraduate Research Day at Queensborough Community College.

Morganella morganii is a gram-negative bacillus with no special arrangement. It is the third member of the tribe Proteeae. This bacterium was first discovered in the year 1906 by a British bacteriologist by the name of He. De R. Morgan. In the late year of 1939, the bacterium was named Proteus morganii, and again changed some years later due to findings that this bacterium did not obtain the ability to ferment all carbohydrates like the genus Proteus was capable of doing. Instead, researchers found the bacterium to have the capabilities of ferment only glucose and therefore its name had been changed one final time to Morganella (its own genus) morganii. While testing M. morganii, findings show that it has its own special characteristics that differ from the usual Proteea. M. morganii does not swarm on a nutrient agar plate like the typical Proteus would. It also does not produce the black precipitate found in Hydrogen Sulfide gas tests. M. morganii produces phenylalanine deaminase, which is the enzyme that wipes out the amino group, resulting in a phenyl pyruvic acid. It is a facultative anaerobe meaning that it is capable of producing energy in the form of ATP by aerobic respiration if oxygen is present in its environment. If oxygen is not present in the environment, the bacteria is fully capable of producing energy in anaerobic environments as well. Morganella morganii can be found in the soil, water, and feces. The bacteria is a common resident to the

“While motility is commonplace among the prokaryotes, it is important to note the variety of structures responsible for motility. These structures vary depending not only on the organism in question, but also on the particular environment” (Bardy, Ng, & Jarrell, 2003). “Study of the bacterial flagellum has provided insights into many aspects of prokaryotic cellular activities including genetics and regulation, physiology, environmental sensing, protein secretion and assembly of complex structures” (Bardy, Ng, & Jarrell, 2003). “Continued study of all prokaryotic motility structures will provide knowledge that is likely to reach far beyond the topic of motility and pathogenicity” (Bardy, Ng,

Finally, our results showed that the bacteria on the +pGLO plate with the amp and ara nutrients had the glowing bacteria. Even though the plate had only one colony of bacteria, it was the only one that glowed. This proves our hypothesis to be partially true because it shows how we were right in choosing the +pGLO plate with all the nutrients to have the glowing bacteria. In conclusion, our hypothesis was half right and half wrong, because the +pGLO with all the nutrients had the only glowing bacteria, but didn;t have the most colonies of bacteria like we first

A magnet can be created by putting a magnet in contact with material such as iron, nickel and aluminum. Magnets can be classified as permanent magnets or ferromagnetic magnets. Permanent magnets are rare earth magnets that have a high

Each batch of phage was used to infect a different culture of bacteria. After infection had taken place, each culture was whirled in a blender, removing any remaining phage and phage parts from the outside of the bacterial cells. Finally, the cultures were centrifuged, or spun at high speeds, to separate the bacteria from the phage debris.

Bacterial pili have been well studied for their structure, function, and genetics. However, little is known about the structure and function of archaeal pili. Current research has begun to focus on the archaeal pilus and its relatedness to bacterial pili, particularly the bacterial type IV pilus. Using genetic and microscopy techniques, these studies have shown comparative evidence for the differences, as well as homology, between archaeal and bacterial type IV pili. These results suggest there may be an evolutionary divergence from a common ancestral function and origin.

Marc Janoschek (http://www.lanl.gov/discover/news-stories-archive/2014/November/janoschek-wolfram-prandl-prize.php) of the Los Alamos Lab says that, on the atomic level, each atom of a metal has a set number of electrons that orbit the nucleus that never changes. This set number of electrons is referred to as the metal in its ‘ground state’. The neutrons and electrons both have a magnetic field that creates an opportunity for the atom to be aligned in another magnetic field.

Ricardo Morales on the synthesis and characterization of bimetallic magnetic nanoparticles for further application in cancer treatment, I gained the skill sets needed to come up with research ideas and implement them as well as how to resolve issues that arise within any research. My experience as a teaching assistant in organic and general chemistry at the University of La Verne Chemistry Department taught me the importance of lab safety and the joys of connecting what is learned in lecture to lab and helping students make that connection in a lab setting while creating a safe environment. My experience as an Academic Success Center tutor in chemistry course from general chemistry to advance organic chemistry taught me the joys of helping students to truly understand material and not memorize it but have that knowledge become a part of them that they can use whether in a research setting or to explain those concepts to their peers. These experiences in undergrad allowed me to determine that academia was the right fit for me; graduate school will give the skills needed to fulfill this

It’s a pretty sweet system, really, although not particularly unique. Genetically similar chemotrophic bacteria have been found in geothermal ocean vents thick with similar

Magnets have intrigued people for a long time; they were discovered long ago. Certain rocks and ores of iron called lodestones were found. These lodestones which were naturally magnetic rocks made of the mineral magnetite, were so mysterious to

Some prokaryotes, such as the myxobacteria (slime bacteria) go through a stage of multicellularity. However there are a few species of the bacteria known as magnetotactic (MTB) are ‘obligatorily multicellular’, meaning that they exist in a multicellular form at all stages in their life cycle. Its cells form a hollow sphere which go through synchronous division. The whole organism reproduces by binary fission.

Figure 6. (A) Structure of the nucleosome core particle with (H3/H4)2 at the center of the DNA wrap and (H2A/H2B)2 docked at the edges, near the DNA entry and exit locations. (B) Nucleosomes control access to certain binding sites. Transient DNA unwrapping exposes the binding sites. As nucleosomes unwrap, H2A/H2B dimers can be lost, exposing more DNA, and when the nucleosome is completely unwrapped, (H3/H4)2 is lost, and DNA is completely exposed. This image was taken from a previous publication (Weber & Henikoff, 2014).

One more interesting property of gadolinium is a magnetocaloric effect. This is a phenomenon where the element increases its temperature in the presence of magnetic fields and vice verse.

It has been observed in some nitrogen-fixing bacteria (Clark, 13). Hydroxamate-type siderophore uses nitrogen atoms of oxazoline and thiazoline to chelate ferric ion. Ferrichrome is an archetypal example of hydroxamate-type siderophore. The third class of siderophore, on top of using N-hydroxy amino side chain together with an oxygen atom, it combines all the three siderophore types and it utilizes three distinctive methods of the binding ferric ion.
